Final answer:
Cytokinesis during oogenesis is unequal, leading to one large oocyte and smaller polar bodies. Human oogonia have 46 chromosomes, which is the diploid number. The unequal cytoplasm distribution ensures the ova have sufficient resources for embryonic development.
Step-by-step explanation:
Cytokinesis during oogenesis is unequal. In oogenesis, which is the process of forming female gametes known as ova or egg cells, there is an asymmetric division of the cytoplasm. This results in the formation of one large cell, which retains most of the cytoplasm, and smaller cells called polar bodies that contain minimal cytoplasm and eventually degrade. The larger cell is the oocyte which, upon fertilization, will provide all the necessary materials needed by the resulting zygote. This is because the zygote derives all its cytoplasmic components from the egg.
Human oogonia have the diploid number of chromosomes, which is 46. These cells are the precursors to oocytes and eventually ova. The unequal distribution of cytoplasm in oogenesis ensures the ova have sufficient resources to support the early stages of embryonic development after fertilization.
